This week in "Up to Speed" we delve into the Psalms and learn how to actually understand what they're talking about, and where the authors were coming from. We wonder why God changes his mind so much, considering he's unchanging and all that. We answer a few listener questions: one about Noah's fascinating great-granddad Enoch, and one about the 10 Commandments-where did they come from? And 10? Why 10? The answer is much more trivial (and amusing) than you'd think. And, because we have trouble going a week without doing so, we describe another monster found in the Bible—this time it's an armor plated dragon that breathes fire. Yes, really.

Special thanks to Tim, Ryan, and Peter for submitting questions used in today's episode.
